I have a 2007 15" MacBook Pro with a broken display. I would like to connect it to a Thunderbolt Display that I have. The MacBook has a DVI Port and I can use a DVI to VGA adapter to connect it to a VGA monitor. When i use the Display with a newer MacBook Pro I just plug the cord with the Thunderbolt symbol into the Thunderbolt port on my 2014 MacBook Pro. How do I get the old MacBook Pro hooked up to the Display? Thanks.
